NAME¶cupsd-helper - cupsd helper programs (deprecated)
SYNOPSIS¶cups-deviced request-id limit user-id options
cups-driverd cat ppd-name
cups-driverd list request_id limit options
cups-exec sandbox-profile [ -g group-id ] [ -n nice-value ] [ -u user-id ] /path/to/program argv0 ... argvN
DESCRIPTION¶The cupsd-helper programs perform long-running operations on behalf of the scheduler, cupsd(8). The cups-deviced helper program runs each CUPS backend(7) with no arguments in order to discover the available printers.
The cups-driverd helper program lists all available printer drivers, a subset of "matching" printer drivers, or a copy of a specific driver PPD file.
The cups-exec helper program runs backends, filters, and other programs. On macOS these programs are run in a secure sandbox.
FILES¶The cups-driverd program looks for PPD and driver information files in the following directories:
/Library/Printers /opt/share/ppd /System/Library/Printers /usr/local/share/ppd /usr/share/cups/drv /usr/share/cups/model /usr/share/ppd
Driver information files must conform to the format defined in ppdcfile(5).
NOTES¶CUPS printer drivers, backends, and PPD files are deprecated and will no longer be supported in a future feature release of CUPS. Printers that do not support IPP can be supported using applications such as ippeveprinter(1).
